I am wondering if anyone has tried building such a beast?
ie a Lunux libusb that will be able to access devices in FreeBSD..
The reason I'd like it is that I want to use this
http://rmdir.de/~michael/xilinx/ in FreeBSD so I can talk to a USB JTAG
cable.
The thing I am not sure about is how ioctl's would get mangled on the
way through.
They get interpreted as linux ioctl, as they are handled by the
linuxulator. You could try to write a wrapper there...
I guess the other approach would be to use a standard Linux libusb but
emulate the device tree it uses in Linux.. Would be a lot of work
though I think.
As long as you can specify the devices in the linux app, it's enough
to translate the ioctl's. Apart from that, there's some kind of
translation layer for devices already, but I don't know if it just a
Linux major/minor -> FreeBSD dev mapping, or if you can map linux dev
-> FreeBSD dev.
AFAIR HPS' USB stack has linux compatibility, maybe you should ask him
/ have a look at it.
Bye,
Alexander.
